Scientists and engineers have always challenged themselves to explore remote places and make new discoveries. To make this possible, they have designed spacecraft, rovers, satellites, and robots that enable them to collect data and make visual observations of previously inaccessible places. They have succeeded many times, but have also failed many times. Remember that failure presents a chance to learn. Use the following ideas to start thinking like a scientist: 1. Scientists send rovers to Mars. 2. They use submarines in water. 3. They fly drones into volcanoes.
